It depends. Larc is talking about travelling into the future which I think is entirely possible, just not now. Travelling back into the past is what people consider impossible and if you just think about you can only agree with that. Just think about the time paradoxes.

If I travel to a different time zone- Have I not effectively traveled time?

One might argue, well, it's the same time, only humans have determined it to be a different time. Well, if that were true, then humans have labeled the past as past and future as future, so in that case, if I "travel back" to one year ago, and have the ability to communicate with those of the present, is it not the same as me going to one time zone ahead of me and communicating with someone?

Get your metaphysics out of my physics. Seriously. That's a completely different topic of discussion. (in which you are probably right)

You cannot accelerate an object of consequential mass to a fast enough speed for it to undergo the relativistic effect. The end. It would require another spatial object of infinite mass, and that's not possible.

Time ago,I've talked with a Japanese girl from Tokio who was already into the night of the next day. (I'm Italian,so 9 hours of difference between her and me) Funny, huh? I don't think she was ahead or behind,if you can chat with a person in real time,it sort of proves that he\she is here and also you are. Just different light of the day I think.

About the ability of talking from the past with a person of the present,I don't think it will be possible....also the guy in question (Titor) wasn't able to do such a thing.

Never heard about Paul Davies? He is a British-born physicist,writer and broadcaster,presently a professor at Arizona State University.In the past has occupied the desk most prestigious of physics in England,that of Cambridge,and he is convinced that a time-machine can be build.The scientists says that In our galaxy exist a Big Black Hole with a mass over a million times the mass of the sun (I know that the Black Holes doesn't have infinite mass,but they have infinite density),and according to the scientists is sufficient....But this is only theory...

Stephen Hawking has proved that if you built a time machine it would explode before you could use it. I'm not sure how he did that, but if you want to throw random names into the ring as your argument, I'd be more than happy to do the same.

For something to accelerate to a substantial speed around the supermassive object at the center of the galaxy, it would have to ENTER the galaxy with a great enough speed to avoid being deflected by any local start or planets, and it would still take a very long time (on the scale of thousands of years) to theoretically reach such a speed. Long enough that anyone on board would die. Time travel is impossible.

1) It's not a random name,Paul Davies ia a physicist,and I've mentioned him because you've talked about physics.2) The Theory of Davies is mentioned also by some "expert scientists" (look the videos if you understand my language)3) Every physician has his own theory,Hawking doesn't believe in time-travel,Davies yes,what's the problem?4) I suggest you to read Paul Davies's book called "How to Build a Time Machine",this book will make your ideas clear.

I see that you like being right,you don't bear someone to think differently from you or what?

The media being slow on internet happenings isn't new. This is very old. If you get your internet news from TV media, you don't belong on the internet. He mentioned things that WILL happen at the end of 2005 that did NOT happen. This is FAKE. Whether or not time travel is real, this is fake.

Jesus Christ, leave some things to die.

With this I close because I don't want to dwell further on....

See what you did right there? You "closed" the argument, getting the last say and effectively dismissing anything else Tipereth had to say. Not to mention it amounts to nothing more than ad hominem. I'd say Tipereth isn't the only person that likes being right. Actually, anyone with human tendencies would like being right.

Anyway, I'm with Tipereth on this. Time travel is not possible. In fact, time doesn't actually "exist". It can't be measured. We have things that have existed in the past up until now and events that have taken place in the past. But time is neither an event nor a thing.

Even the act of moving forward in time (which is actually called time dilation and not time travel btw) as you've stated is impossible. Light has no mass. Considering all of the practical limitations and complications, there is no way an object WITH mass will be able to accelerate to a speed even remotely close to light. Actually, Tipereth already said this, but instead of refuting this point you've offered the "anything is possible" fallacy.

Hey, in a million years I'm going to have a penis the size of Jupiter using an enlargement ray. And there's nothing wrong with that.
